This is my firts post in the forum, so first of all I apologize for all kind of mistakes, past, present and future.
After this bad presentation, here is my question:
In an existing mailserver, made with postfix and dovecot, I found configurations related to virtual alias made like email@example.com –> firstname.lastname@example.org
So, users can connect to the server using thunderbird et simila directly on email@example.com
How can I replicate this in mailcow?
